So I am noticing my MBP getting rather hot. So much so that I also hear the fans spool up. I have a CPU usage gadget installed and I see each core randomly getting spiked at 100%. Never all cores at once though. It so quickly randomly hits each core at 100% that it begins to make sense why she's running hot. This happens when simply playing MODs with Eagle Player.

I don't see this behavior with WinUAE under Windows. Even when running Windows emulated under Parallels inside OSX.
